BOSTON (CBS) – A Newbury Street coffee shop has been given the green light to re-open after being closed by Boston Inspectional Services for two days because of concern for measles exposure.

Officials say a woman travelling from Europe visited Nespresso on May 4 and was later treated for measles at Massachusetts General Hospital. Lab tests confirmed the highly contagious virus.

City health officials were concerned that other patrons and employees were exposed to measles potentially spreading the virus. “We need to verify anyone working in the establishment is already immune to measles, that they’re not going to spread it to others,” said Dr. Anita Barry with the Boston Public Health Commission.

Inspectional Services called the store managers to a hearing on Friday demanding to know why repeated requests for a list of workers on the job that day was not provided. Assistant manager Larry Williams could only say he was following protocol and had reached out to corporate managers in New York.

The concern is mostly for the unvaccinated, but the warning got a lot of attention on Newbury Street, especially from frequent customers. “Just not knowing too much about it, there’s too many diseases these days to be protected. I need to get informed,” said Samantha Sugarman.
